    Frequently Asked Questions

      
What's the difference between JSON and YAML?
Both are data serialization formats. JSON uses braces and brackets with strict syntax. YAML uses indentation and is more human-readable. YAML is a superset of JSON, meaning valid JSON is also valid YAML.

      
When should I use YAML vs JSON?
YAML is preferred for configuration files (Docker, Kubernetes, GitHub Actions) where readability matters. JSON is preferred for APIs, data exchange, and programmatic use where strict parsing is important.
